Abstract
A voltage monitoring arrangement including a number of comparison devices, which corresponds to a prescribed number of voltage ranges, compares the value of an input voltage with a reference voltage and outputs a prescribed signal if the input voltage is within one of the prescribed voltage ranges. The voltage monitoring arrangement has a latch circuit which, when a latch signal is applied, establishes which voltage range the input voltage is currently in when the latch signal is applied, resulting in the arrangement having automatic voltage range reduction. The voltage monitoring arrangement has a monitoring unit which outputs a predetermined signal if the input voltage is outside the voltage range which exists when the latch signal is applied.
